Description and Introduction

Adjustable, 1.5-A Switch, 96% Efficient Boost Converter w/ LDO Down-Mode, QFN-10 The TPS61020DRCRG4 is a boost converter manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 1.8V to 5.5V  
- **Output Voltage Range:** Adjustable from 2.5V to 5.5V  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 19µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** VSON-10 (DRC)  

### **Descriptions:**  
The TPS61020DRCRG4 is a high-efficiency, low-quiescent-current boost converter designed for battery-powered applications. It integrates a synchronous rectifier to improve efficiency and supports low input voltages, making it suitable for single-cell or dual-cell alkaline/NiMH battery applications.  

### **Features:**  
- **Synchronous Boost Converter:** Improves efficiency by eliminating the need for an external diode.  
- **Low Start-up Voltage:** Operates down to 1.8V input.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **Power-Save Mode:** Enhances efficiency at light loads.  
- **Thermal Shutdown & Overcurrent Protection:** Ensures safe operation.  
- **Small Footprint:** 10-pin VSON package (3mm x 3mm).  

This device is commonly used in portable electronics, IoT devices, and other low-power applications requiring efficient voltage conversion.

Application Scenarios & Design Considerations

Adjustable, 1.5-A Switch, 96% Efficient Boost Converter w/ LDO Down-Mode, QFN-10

Alternative Part Number

  • TPS61020DRCR --: Same TPS61020 boost converter in the same 10-pin VSON package, identical electrical specifications; the G4 suffix only denotes lead-free/RoHS green packaging, so this is a drop-in replacement.
  • TPS61025DRCR --: Pin-compatible member of the same TPS6102x boost converter family with the same package and pinout, offering a slightly different fixed output voltage; suitable when the output setpoint can be adjusted.
  • TPS61220DRCR --: Similar TI boost converter in the same small VSON package with comparable input range and current capability; a viable alternative when minor differences in switching frequency and output voltage are acceptable.
